CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2018-0093137, filed on Aug. 9, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The disclosure relates to an electronic device including a button for a user information input and a method for an operation in the electronic device.

BACKGROUND

Recently, electronic devices have evolved into various types for user convenience.

Electronic devices have evolved into various types, such as an input means for an input interface used to manipulate an external electronic device and to input user information by the external electronic device. Such input means include an electronic device having a pen function (for example, a stylus or an electronic pen), and user information may be input to an external electronic device including a touchscreen through the touchscreen of the external electronic device.

Electronic devices having the pen function commonly adopt an electromagnetic resonance (EMR) type among input types, and a Bluetooth function-based input type has recently been developed.

An electronic device having a pen function tends to be configured such that the same can be mounted on an external device in view of the user's convenience and portability of the device, or such that the device size is made smaller, and may have a button as an input interface for a user input.

In order to apply various functions or various input types, however, one single button needs to be used to perform one function, or other buttons corresponding to various input types need to be provided additionally.

However, adding and configuring buttons makes the structure of the electronic device complicated, and if the electronic device is accordingly configured to be mounted on an external device, the external device needs to have a large mounting space and becomes complicated.

In addition, if a Bluetooth function is applied as another input type to the electronic device, the Bluetooth function operates every time the user conducts a button input and quickly reduces the current in the small-capacity battery. This may cause inconvenience in using the electronic device.

SUMMARY

According to various embodiments, an electronic device including a button and a method is provided, wherein an EMR input type or a Bluetooth low energy (hereinafter, referred to as BLE) input type is selectively determined according to whether or not an approach signal is identified, thereby reducing battery current consumption.

According to various example embodiments, an electronic device may include: an elongated housing including a first end and a second end; a dielectric tip disposed at the first end; a button arranged on an outer surface of the housing; a first circuit connected to the dielectric tip and configured to receive a first electromagnetic signal from a touchscreen display of an external device and to transmit a second electromagnetic signal to the display of the external device; a second circuit configured to wirelessly receive and transmit a third signal; and a control circuit operatively connected to the first circuit and the second circuit. The control circuit may be configured to: detect pressing and/or touching of the button while the first electromagnetic signal is received through the first circuit and transmit the second electromagnetic signal while preventing the second circuit from transmitting the third signal; and detect pressing or touching of the button without receiving the first signal through the first circuit and transmit the third signal while the second signal is not transmitted.

According to various example embodiments, an electronic device may include: an elongated housing including a first end and a second end; a dielectric tip disposed at the first end; a button arranged on an outer surface of the housing; a first communication unit comprising first communication circuitry connected to the dielectric tip and configured to receive a first electromagnetic signal from a touchscreen display of an external device and to transmit a second electromagnetic signal to the display of the external device; a second communication unit comprising second communication circuitry configured to wirelessly receive and transmit a third signal; a processor operatively connected to the first communication unit and the second communication unit; and a memory electrically connected to the processor. The memory may include instructions that, when executed, cause the processor to control the electronic device to: transmit the second signal to the external device while preventing a third signal from being transmitted through the second communication unit in response to pressing and/or touching of the button, while the first signal is received through the first communication unit; and transmit the third signal to the external electronic device through the second communication unit in response to pressing and/or touching of the button, while the first signal is not received through the first communication unit.

According to various example embodiments, a method for an operation in an electronic device including a button for a user information input may include: receiving a first electromagnetic signal from a touchscreen display of an external device; detecting pressing and/or touching of the button; transmitting a second electromagnetic signal to the display of the external device, while preventing a third signal from being transmitted through a first communication unit, in response to pressing or touching of the button while the first signal is received; and transmitting the third signal to the external device through a second communication unit in response to pressing and/or touching of the button without receiving the first signal.

An electronic device and a method for an operation in the electronic device according to various example embodiments may have at least the following advantages: the electronic device detects pressing and/or touching of a button, selectively determines an EMR input type or a BLE input type according to whether or not an approach signal is identified, and transmits a signal that follows the determined input type to an external electronic device. Accordingly, there is no need to additionally configure a separate button, and the BLE operation resulting from button pressing is minimized and/or reduced, thereby reducing battery current consumption; and the actual time of use of the Bluetooth module is accordingly reduced.

In various example embodiments described below, an electronic device having a pen function for inputting user information (for example, the electronic device 102 of FIG. 1) may be described as a first electronic device, and the electronic device 101 of FIG. 1 may be described as a second electronic device, which is an external electronic device.

Hereinafter, the first electronic device and the second electronic device according to various embodiments will be described with reference to the accompanying drawings.

FIG. 2 is a diagram illustrating an example configuration of the first electronic device and the second electronic device according to various embodiments.

Referring to FIG. 2, the first electronic device 201 according to various embodiments may be configured such that the first electronic device 201 can be mounted on (or within) the second electronic device 101 and may be configured as an input device for inputting a user interface to a display 203 (for example, the display device 160 of FIG. 1) having a touchscreen of the second electronic device 101.

The second electronic device 101 may include an insertion opening 207 configured such that the first electronic device 201 can be inserted therein from a side surface of the housing 205 of the second electronic device 101. The second electronic device 101 may include an antenna (not illustrated) (for example, the antenna module 197 of FIG. 1) inside the insertion opening 207 such that the first electronic device 201 can communicate outside the same.

The first electronic device 201 may operate differently in a state in which the first electronic device 201 is inserted into the insertion opening 207 and in a state in which the first electronic device 201 is ejected or withdrawn from the insertion opening 207. According to various embodiments, the first electronic device 201 may be configured such that the first electronic device 201 is provided separately without being inserted into the second electronic device 101.

FIG. 3 is a diagram illustrating an example configuration of a second electronic device based on an EMR input type according to embodiments.

Referring to FIG. 3, the touchscreen 301 included in the display (for example, the display 203 of FIG. 2) of the second electronic device 101 may include a display panel 310, a first touch panel 320, and a second touch panel 330. The display panel 310 may be a panel such as, for example, and without limitation, an LCD, an AMOLED, or the like, and may display various images related to various operating states of the second electronic device 101, application execution, services, and the like.

The first touch panel 320 may, for example, be a capacitance-type touch panel obtained by, for example, coating one surface of glass or both surfaces thereof with a thin metal conductive material (for example, indium tin oxide (ITO) film) such that the glass surface is coated with a dielectric material which enables a current to flow and which can store an electric charge. If an input instrument (for example, the user's finger or an electronic pen) touches the surface of the first touch panel 320, a predetermined amount of electric charge is moved to the touched position by static elasticity, and the first touch panel 320 can sense the touched position by recognizing the amount of current change resulting from the movement of the electric charge. Through the first touch panel 320, any kind of touch capable of generating static elasticity can be sensed, including all touches by the input instrument (finger or electronic pen).

The second touch panel 330 may, for example, be an EMR-type touch panel, and may include an electromagnetic induction coil sensor (not illustrated) having multiple loop coils arranged in a first direction and in a second direction that intersects with the first direction, respectively, thereby having a grid structure, and an electronic signal processing unit (not illustrated) configured to successively provide AC signals having a predetermined frequency to respective coils of the electromagnetic induction coil sensor. If the first electronic device 201 including a resonance circuit is near a loop coil of the second touch panel 330, the magnetic field (electromagnetic field) transmitted from the corresponding loop coil may generate a current based on mutual electromagnetic induction in the resonance circuit inside the first electronic device 201. If an induced magnetic field is generated, on the basis of the current, by the coil of the resonance circuit inside the first electronic device 201, the second touch panel 330 may detect the induced magnetic field from the loop coil in a signal-receiving state, thereby sensing the hovering position of the first electronic device 201, the touch position, and/or the height from the second electronic device 101 to the first electronic device 201.

According to an embodiment, the second electronic device 101 may enable the first touch panel 320 to sense a touch by the user's finger and/or an electronic pen and may enable the second touch panel 330 to sense hovering by the first electronic device 201 and/or a touch thereby. Accordingly, the processor (for example, the processor 120 of FIG. 1) of the second electronic device 101 may differently sense a touch by the user's finger or the electronic pen and hovering or a touch by the first electronic device 201.

According to an embodiment, the display panel 310 may be arranged between the first touch panel 320 and the second touch panel 330. The first touch panel 320 may be provided such that the same is stacked on the inner surface of the front glass of the second electronic device 101. However, the disclosure is not limited to any particular arrangement of the panels.

FIG. 4 is a diagram illustrating an example configuration of a first electronic device according to various embodiments.

Referring to FIG. 4, the first electronic device 201 according to various embodiments may include an elongated housing 400 including a first end 401 and a second end 403. The housing 400 may be divided into a first part 410 and a second part 420 and may be configured such that the first part 410 and the second part 420 can be attached to/detached from each other. The first electronic device 201 may include a button 411 arranged on the outer surface of the first part 410, an EMR coil unit 413 including a dielectric tip 415 inside the first end 401, and at least one module (not illustrated) for operations inside the housing 400. The at least one module may be configured, for example, as a printed circuit board (PCB), and the PCB may be electrically connected to the EMR coil unit 413. The first electronic device 201 may further include a push button 421 on or at the second end 403 of the second part 420 such that the push button 421 may be used when the first electronic device 201 is inserted into the insertion opening 207 (of FIG. 2) or ejected therefrom. If the push button 421 reaches a pressed state, the first electronic device 201 may be ejected from the insertion opening 207, and may switch to an ejected state.

The first electronic device 201 may selectively determine the type of input through the button 411 between an EMR input type and a Bluetooth low energy (hereinafter, referred to as BLE) input type and may transmit a signal that follows an input (e.g., a user input) to the second electronic device 101.

FIG. 5 is a block diagram illustrating an example configuration of a first electronic device and a second electronic device according to various embodiments.

Referring to FIG. 5, the first electronic device 201 according to various embodiments may include a processor (e.g., including processing circuitry) 511, a first communication unit (e.g., including communication circuitry) 513, a second communication unit (e.g., including communication circuitry) 515, a memory 517, and a battery 519. The first electronic device 201 may further include a button (not illustrated) (for example, the button 411 of FIG. 4) arranged on the outer surface of the housing. According to various embodiments, the processor 511 of the first electronic device 201, at least a part of the first communication unit 513, and at least a part of the second communication unit 515 may, for example, be configured as PCBs or chips, and may be electrically connected to the memory 517, the battery 519, and the button.

The processor 511 may include various processing circuitry and receive an approach signal (for example, a first signal) corresponding to an electromagnetic field signal generated by the touchscreen (for example, the touchscreen 301 of FIG. 3) of the second electronic device 101 through the first communication unit 513. The approach signal may refer, for example, to a signal used to determine whether the first electronic device 201 is positioned in-range on the touchscreen 301 of the second electronic device 101.

According to various embodiments, if the approach signal is confirmed while the button of the first electronic device 201 is in a pressed or touched state, the processor 511 may confirm that the button input corresponds to a first communication input type (for example, EMR button input), and may control the first communication unit 513 so as to transmit a second signal (for example, an EMR input signal) to the second electronic device 101.

According to various embodiments, if the approach signal is not confirmed while the button is in a pressed or touched state, the processor 511 may confirm that the button input corresponds to a second communication input type (for example, a BLE button input), and may control the second communication unit 515 so as to transmit a third signal (for example, a BLE input signal) to the second electronic device 101. The processor 511 may selectively determine the second communication input type (for example, a BLE button input) based on receiving the approach signal even if the user uses only one button, and the processor 511 may accordingly control transmission of the third signal while the second signal is not transmitted.

According to various embodiments, the processor 511 may include an operation circuit for determining whether the first electronic device 201 is positioned in-range on the touchscreen 301 of the second electronic device 101.

The processor 511 may, for example, be a hardware module and/or a software module (for example, an application program), and may, for example, be a hardware-based element (function) and/or a software-based element (program) including at least one of various sensors provided in the first electronic device 201, such as, for example, and without limitation, a data measurement module, an input/output interface, a module for managing the state or environment of the first electronic device 201, a communication module, or the like. According to various embodiments, the processor 511 may include, for example, and without limitation, one or more of hardware, software, firmware, and/or a combination of at least two thereof. In addition, according to various embodiments, at least some of the above elements of the processor 511 may be omitted, or the same may further include another element for performing image processing operations besides the above constituent elements.

According to various embodiments, the first communication unit 513 may include various communication circuitry and transmit/receive a signal for a user interface to/from the second electronic device 101 using the EMR input type, for example, and may include an EMR coil unit (for example, identical or similar to the EMR coil unit 413 of FIG. 4) capable of generating an electromagnetic field. The first communication unit 513 may include at least one element (for example, a resistor, a capacitance C, and/or an inductance) that makes it possible to change the intensity or frequency of the electromagnetic field according to the manipulation state. The first communication unit 513 may include a button switch SW1 (not illustrated) that is turned on in response to the user's pressing and/or touching of the button (for example, the button 411 of FIG. 4) arranged on the surface of the housing of the first electronic device 201.

The first communication unit 513 may receive an approach signal corresponding to an electromagnetic field signal (or an electromagnetic signal) generated by the second electronic device 101 as a result of proximate positioning of the first electronic device 201 on the touchscreen 301 of the second electronic device 101. Upon sensing pressing and/or touching of the button by the user, the first communication unit 513 may transfer a button input signal to the processor 511. Upon sensing pressing and/or touching of the button by the user, the first communication unit 513 may change the frequency of the electromagnetic field signal generated by the EMR coil unit (for example, the EMR coil unit 413 of FIG. 4). The first communication unit 513 may transmit a second signal corresponding to the electromagnetic field signal, the frequency of which has been changed, to the second electronic device 101 under the control of the processor 511. The electromagnetic field signal, the frequency of which has been changed, may be transmitted when a button input has been received, and when an approach signal has been received. In the following description, an electromagnetic field signal having a first frequency generated when the button is turned off will be referred to as a first electromagnetic field signal, and an electromagnetic field signal having a second frequency generated when the button is turned on will be referred to as a second electromagnetic field signal.

According to various embodiments, the second communication unit 515 may include various communication circuitry in a module for a near-field communication, that is, a second communication type (for example, a BLE input type), and may transmit a third signal (for example, a BLE signal) to the second electronic device 101 in the second communication type under the control of the processor 511. If it is confirmed by the processor 511 that no approach signal is received, and that a button input signal is received, the second communication unit 515 may recognize that the button input is a BLE button input, and may transmit the third signal to the second electronic device 101. When a button input signal and a approach signal are received, a second signal is transmitted through the first communication unit 513. Accordingly, the second communication unit 515 may not transmit the third signal while the second signal is transmitted under the control of the processor 511.

FIG. 6 is a diagram illustrating an example circuit configuration of a first electronic device according to various embodiments.

Referring to FIG. 6, the first electronic device 201 according to various embodiments may include a first circuit 610, a second circuit 620, a third circuit 630, a control circuit 640, and a battery 650. According to various embodiments, the first electronic device 201 may include the third circuit 630 in the first circuit 610. According to various embodiments, the first electronic device 201 may include an instrumentality capable of providing vibration or friction (not illustrated), such as an actuator.

The first circuit 610 may, for example, be an EMR input-type circuit, for example, and may include a resonance circuit (for example, the EMR coil unit 413 of FIG. 2) including a first inductive element (for example, a coil) 611 capable of generating an electromagnetic field and a first capacitive element (for example, a capacitance C1) 613. In addition, the first circuit 610 may include at least one element (for example, a resistor R, a capacitance C, and/or an inductance L) that makes it possible to change the intensity or frequency of the electromagnetic field according to the manipulation state. The first circuit 610 may include a button switch SW1 615 that is turned in response to the pressing and/or touching of the button (for example, the button 411 of FIG. 4) arranged on the surface of the housing of the first electronic device 201. According to various embodiments, the coil 611 may have a resonance frequency in about 500 KHz band, for example. The first circuit 610 may form at least two resonance frequencies (for example, 530 KHz and 560 KHz bands), and may change the resonance frequency by a variable capacitance. For example, the first resonance frequency (for example, 560 KHz band) may correspond to a drawing operation, and the second resonance frequency (for example, 530 KHz) may correspond to a button operation. At least one capacitance Cf and rectifiers D1 and D2 may be additionally arranged between the first circuit 610 and the control circuit 640 and connected to the battery 650 and the third switch M3 645. The first rectifier D1 among the rectifiers may become conductive if an AC-type resonance voltage Vres generated by the resonance circuit included in the first circuit 610 is smaller than zero (Vres<0). Accordingly, the capacitance Cf may be filled with a voltage corresponding to the negative peak of the voltage Vres. If the voltage Vres increases, the first rectifier D1 may be turned off, and the second rectifier D2 may reach a conductive condition. If the second rectifier D2 reaches the conductive condition, the electric charge in the capacitor Cf may move to the battery 650 through the control circuit 640, thereby changing the battery 650.

If the button switch 615 is switched on in response to the user's pressing and/or touching of the button 411, the first circuit 610 may be connected to the control circuit 640 so as to transfer a button input signal to the control circuit 640, and may change the frequency (or resonance frequency) of an electromagnetic field signal generated by the induction current in the coil 611. The button input signal may indicate a current resulting from pressing or touching of the button.

If an approach signal A is received, and if a button input signal B is generated, the first circuit 610 may transmit, to the second electronic device 101, a second signal corresponding to a second electromagnetic field signal having a changed second frequency.

The second circuit 620 may include a module including various communication circuitry for near-field communication, that is, a second communication type (for example, a BLE input type) and may be connected to the control circuit 640. The second circuit 620 may receive control signals (for example, a first control signal 601 (for example, /A) corresponding to an approach signal (A) and a second control signal 603 (for example, BLE BUTTON) corresponding to a button input signal (B)) output from the control circuit 640 and may transmit a third signal (for example, a BLE signal) to the second electronic signal 101 in the second communication type on the basis of the received control signals 601 and 603. According to various embodiments, the second circuit 620 may check an EMR button value and a BLE button value on the basis of the first control signal (for example, /A) 601 and the second control signal (for example, BLE BUTTON) 603 output from the control signal 640 and, if the checked BLE button value indicates 1, may transmit the third signal to the second electronic device 101.

According to various embodiments, the second circuit 620 may receive operation result values (for example, /A value and /BLE BUTTON value) from the control circuit 640 and may transmit the third signal to the second electronic device 101 based on the operation result values. The operation result values may include the EMR button value and the BLE button value that have been checked on the basis of the approach signal A (for example, the first signal) and the button input signal B.

The third circuit 630 may include at least one resistor, a capacitance, and/or a rectifier, and may include a fourth switch M4 631 and a voltage detection circuit 633. The fourth switch M4 may be connected to the third switch M3 645 of the control circuit 640. The voltage detection circuit 633 may monitor the voltage Vm.

The third circuit 630 may be arranged between the first circuit 610 and the battery 650 and may be connected to the resonance circuit of the first circuit 610, the first switch M1 641 of the control circuit 640, and the third switch M3 645 connected to the battery 650. The third circuit 630 may receive an approach signal (for example, a first signal) corresponding to an electromagnetic field signal generated by the touchscreen 301 of the second electronic device 101, and may transfer the received approach signal to the first switch M1 641 of the control circuit 640.

The control circuit 640 may be electrically connected to the first circuit 610, the third circuit 630, the second circuit 620, and the battery 650. The control circuit 640 may include a first switch M1 641, a second switch M2 643, and a third switch M3 645, and may include at least one capacitance C2 647 and resistors R (R1, R2, R3 649, and R4). The capacitance C2 647 may be arranged between the resistor R3 649 and the second circuit 620, and may be electrically connected to the resistor R3 649, the second circuit 620, and the ground. The capacitance C2 647 and the resistor R3 649 may be elements performing operations of low-pass filters so as to prevent erroneous operations of the second circuit 620 due to the operating voltage of the first electronic device 201, which is transferred from Vres when the first switch SW1 615 is turned off. According to various embodiments, the control circuit 640 may include an operation circuit for determining whether or not the first electronic device 201 is positioned in-range on the touchscreen 301 of the second electronic device 101.

The control circuit 640 may receive the button input signal B from the first circuit 610 and receive the approach signal A from the third signal 630. According to various embodiments, if the approach signal A is transferred, and if the button input signal B is transferred, the control circuit 640 may not transfer the button input signal B to the second circuit 620, and may control the first circuit 610 so as to transmit the second signal. According to various embodiments, if the approach signal A is not transferred, and if the button input signal B is transferred, the control circuit 640 may transfer the button input signal B to the second circuit 620 such that the second circuit 620 transmits the third signal. In response to transfer of the button input signal, the second circuit 620 may recognize a low signal voltage (low signal or active-low) and may process information.

The battery 650 may be connected to the third switch M3 645 of the control circuit 640 and the ground, may store power necessary for overall operations, and may be rechargeable or non-rechargeable.

A method for an operation in the above-described first electronic device 201 will be described in greater detail with reference to the accompanying drawings.

FIG. 7 is a flowchart illustrating an example method for operating a first electronic device according to various embodiments. FIG. 8A is a diagram illustrating an example operation between a first electronic device and a second electronic device according to various embodiments. FIG. 8B is a diagram illustrating an example operation between a first electronic device and a second electronic device according to various embodiments.

Referring to FIG. 7, the first electronic device 201 according to various embodiments may confirm whether a button input signal has been generated by pressing and/or touching a button (for example, the button 411 of FIG. 4) in operation 701. When it is confirmed that a button input signal has been generated, the first electronic device 201 may perform operation 703 and, if no button input signal has been generated, the first electronic device 201 may perform operation 701 again.

In operation 703, the first electronic device 201 may confirm whether an approach signal (for example, a first signal) generated based on an electromagnetic field signal generated by a coil (for example, the coil 611 of FIG. 6) has been received. When it is confirmed that the approach signal has been received, the electronic device 201 may perform operation 705 and, if no approach signal has been received, the first electronic device 201 may perform operation 707.

In operation 705, when the approach signal has been received, the first electronic device 201 may confirm that, as illustrated in FIG. 8A, the same is positioned in-range on the touchscreen 801 (for example, the touchscreen 301 of FIG. 3) of the second electronic device 101. Accordingly, the first electronic device 201 may transmit a second signal (for example, an EMR signal) to the second electronic device 101 through a first communication unit (for example, the first communication unit 513 of FIG. 5 or the first circuit 610 of FIG. 6) that uses an EMR input type.

In operation 707, when the approach signal is not received, the first electronic device 201 may confirm that, as illustrated in FIG. 8B, the same is out-of-range on the touchscreen 801 of the second electronic device 101. Accordingly, the first electronic device 201 may transmit a third signal (for example, a BLE signal) to the second electronic device 101 through a second communication unit (for example, the second communication unit 515 of FIG. 5 or the second circuit 620 of FIG. 6) that uses a BLE input type.

The above-described operation method illustrated in FIG. 7 will be described in greater detail with reference to the circuit configuration of the first electronic device 201.

FIG. 9A is a diagram illustrating an example circuit configuration illustrating an example method of operating a first electronic device according to various embodiments. FIG. 9B is a diagram illustrating an example circuitry configuration illustrating an example method of operating a first electronic device according to various embodiments.

Referring to FIG. 9A, if the first electronic device 201 according to various embodiments is positioned in-range on the touchscreen (for example, the touchscreen 301 of FIG. 3 or the touchscreen 801 of FIG. 8A and FIG. 8B) of the second electronic device 101, the same may receive an electromagnetic field signal generated by the second electronic device 101 in the first circuit 610. The first electronic device 201 may generate an electromagnetic field signal by means of an induction current in the first circuit 610 which is generated by the received electromagnetic field signal. Accordingly, a voltage Vm (for example, 0.5V or higher) may be applied to the first path 901 of the third circuit 630 connected to the first circuit 610, and the third circuit 630 may receive an approach signal applied to the first path 901 and may transfer the received approach signal to the control circuit 640 through the second path 902. The approach signal may indicate a first signal corresponding to the first electromagnetic field signal. Accordingly, the first switch M1 641 and the second switch M2 643 of the control circuit 640 may be turned on by the transferred approach signal. When the button switch SW1 is turned off, the first circuit 610 and the control circuit 640 are in short-circuited states, and no voltage is applied to the third path 903. In this case, the button input signal (SW1 signal) may not be transferred to the control circuit 640 through the fourth path 904. According to various embodiments, the capacitance C2 647 and the resistor R3 649 included in the control circuit 640 may perform operations of low-pass filters so as to prevent erroneous operations of the second circuit 620 due to the operating voltage of the first electronic device 201, which is transferred from Vres when the first switch SW1 615 is turned off. The second circuit 620 may operate when the input is zero as a result of an active-low operation. That is, when the input value of the second control signal 913 is zero, the second circuit 620 may recognize that the button (for example, the button 411 of FIG. 4) of the first electronic device 201 is pressed.

Although it has been assumed in the above description of various embodiments with reference to FIG. 9A that the second circuit 620 is activated when receiving a low signal according to an active-low operation, the second circuit 620 may be activated when receiving a high signal according to an active-high operation in another embodiment.

According to various embodiments, when the first electronic device 201 is positioned in-range on the touchscreen 301 of the second electronic device 101, and when the same senses pressing or touching of the button arranged on the surface of the housing, the button switch SW1 615 of the first circuit 610 may be turned on, and the first circuit 610 may transfer a button input signal B to the control circuit 640 through the third path 903. In this case, the resonance circuit of the first circuit 610 may generate an electromagnetic field signal (for example, a second electromagnetic field signal), the frequency of which is changed. According to various embodiments, if the control circuit 640 receives a button input signal B through the third path 903, and if the same receives an approach signal A from the third circuit 630, the same may transfer a first control signal 911 corresponding to the approach signal A and a second control signal 913 corresponding to the button input signal B to the second circuit 620 through the sixth path 906 such that the second circuit 620 does not transmit a third signal.

According to various embodiments, the control circuit 640 may transfer operation result values, which are obtained by operations based on the approach signal and the button input signal, to the second circuit 620 such that the second circuit 620 does not transmit a third signal. The operation result values may include an EMR button value and/or a BLE button value for determining the button input type. Since the second circuit 620 operates according to active-low, the second circuit 620 may transmit a third signal to the second electronic device when the BLE button value (operation result value) is zero.

Although it has been assumed in the above description of various embodiments with reference to FIG. 9A that the second circuit 620 is activated when the input is zero according to an active-low operation, the second circuit 620 may be activated when the input is one according to an active-high operation in another embodiment.

According to various embodiments, when the first electronic device 201 is positioned in-range on the touchscreen 301 of the second electronic device 101, and when pressing or touching of the button arranged on the surface of the housing is not sensed, the control circuit 640 may recognize that the value of the approach signal A is 1 as a result of receiving the approach signal A, as in Table 1 below, and may recognize that the value of the button input signal B is 1 as the button switch SW1 615 is turned off. After recognizing the value of the approach signal A as 1 and recognizing the value of the button input signal B as 1, the control circuit 640 may determine, through operations, that the value of the EMR button EMR BUTTON is 0, and the value of the inverted BLE button BLE BUTTON is 0. Accordingly, the second circuit 620 may recognize that the value of the EMR button EMR BUTTON is 0, and the value of the BLE button is 1, as illustrated in FIG. 9A.

When the first electronic device 201 is positioned in-range on the touchscreen 301 of the second electronic device 101, and when pressing or touching of the button arranged on the surface of the housing is sensed, the control circuit 640 may recognize that the value of the approach signal A is 1 as a result of receiving the approach signal A and, as in Table 1 below, and may recognize that the value of the button input signal B is 0 as the button switch SW1 615 is turned on. After recognizing the value of the approach signal A as 1 and recognizing the value of the button input signal B as 0, the control circuit 640 may determine, through operations, that the value of the EMR button EMR BUTTON is 1, and the value of the inverted BLE button /BLE BUTTON is 0.

As given in Table 1 above, when the approach signal A is 1, and when the EMR button EMR BUTTON value is 0, the first circuit 610 may not transmit a second signal (for example, an EMR signal) corresponding to a second electromagnetic field signal, the frequency of which is changed, and the second circuit 620 may not transmit a third signal (for example, a BLE signal).

In addition, as given in Table 1 above, when the approach signal A is 1, and when the EMR button EMR BUTTON value is 1, the first circuit 620 may transmit the second signal, and the second circuit 620 may not transmit the third signal (for example, a BLE signal) after recognizing that the BLE button value is 1 on the basis of the value of the inverted BLE /BLE BUTTON.

Referring to FIG. 9B, when a voltage is applied to the first circuit 610 of the first electronic device 201 according to various embodiments, a first electromagnetic field may be generated by the resonance circuit including a coil L 611 and a capacitance C1 613. When the first electronic device 201 is positioned out-of-range on the touchscreen 301 of the second electronic device 101, the first circuit 610 may not receive an electromagnetic field signal from the second electronic device 101. Accordingly, the third circuit 630 connected to the first circuit 610 may not receive an approach signal A corresponding to the electromagnetic field signal, and the approach signal A may not be transferred through the fifth path 905. When the button switch SW1 615 is turned off, the first circuit 610 and the control circuit 640 are in short-circuited states, and no voltage is applied to the third path 903. In this case, the button input signal B may not be transferred to the control circuit 640. According to various embodiments, the capacitance C2 647 and the resistor R3 679 included in the control circuit 640 may perform operations of low-pass filters so as to prevent erroneous operations of the second circuit 620 due to the operating voltage of the first electronic device 201, which is transferred from Vres when the first switch SW1 615 is turned off. The second circuit 620 may operate when the input is 0 as a result of an active-low operation. That is, when the input value of the second control signal 913 is 0, the second circuit 620 may recognize that the button (for example, the button 411 of FIG. 4) of the first electronic device 201 is pressed. Although it has been assumed in the above description of various embodiments with reference to FIG. 9B that the second circuit 620 is activated when the input is 0 according to an active-low operation, the second circuit 620 may be activated when the input is 1 according to an active-high operation in another embodiment.

According to various embodiments, when positioned out-of-range on the touchscreen of the second electronic device 101, and when pressing or touching of the button arranged on the surface of the housing is sensed, the button switch SW1 615 of the first circuit 610 is turned on, and a voltage is applied to the third path 903. As a result, a button input signal B may be transferred to the control circuit 640 through the third path 903.

According to various embodiments, when the first electronic device 201 is positioned out-of-range on the touchscreen 301 of the second electronic device 101, the fourth switch M4 631 and the third switch M3 645 may be turned off, as in Table 2 below, and the first switch M1 641 and the second switch M2 643 of the control circuit 640 may be turned off because the approach signal A is not received by the control circuit 640.

According to various embodiments, when the first electronic device 201 is positioned out-of-range on the touchscreen 301 of the second electronic device 101, and when pressing or touching of the button is not sensed, the control circuit 640 may recognize that the value of the approach signal A is 0 because no approach signal A is received, as in Table 2 below, and may recognize that the value of the button input signal B is 1 as the button switch SW1 is turned off. After recognizing the value of the button input signal B as 1, the control circuit 640 may recognize that the value of the inverted BLE button BLE BUTTON is 0, and the value of the EMR button EMR BUTTON is 0.

According to various embodiments, when the first electronic device 201 is positioned out-of-range on the touchscreen 301 of the second electronic device 101, and when pressing or touching of the button is sensed, the control circuit 640 may recognize that the value of the approach signal A is 0 because no approach signal A is received, as in Table 2 below, and may recognize that the value of the button input signal B is 0 as the button switch SW1 is turned on. A first control signal 911, which indicates that the value of the approach signal A is 0, and a second control signal 913, which indicates that the value of the button input signal B is 0, may be transferred to the second circuit 620 through the sixth path 906 such that the second circuit 620 transmits a third signal. According to various embodiments, after recognizing the value of the button input signal B as 0, the control circuit 640 may recognize, through operation results, that the value of the inverted BLE button BLE BUTTON is 1, and the value of the EMR button EMR BUTTON is 0.

As given in Table 2 above, when the approach signal value is 0, when the value of the inverted BLE button BLE BUTTON value is 0, and when the value of the button input signal B is 1, the second circuit 620 may not transmit a third signal (for example, a BLE signal) as a result of recognizing that value of the BLE button is 1 on the basis of the value of the inverted BLE button. In addition, when the approach signal value is 0, when the value of the inverted BLE button BLE BUTTON value is 1 and when the value of the button input signal B is 0, the second circuit 620 may transmit a third signal (for example, a BLE signal) to the second electronic device 101 as a result of recognizing that the value of the BLE button is 0 on the basis of the value of the inverted BLE button.

The control circuit 1030 may receive an approach signal A corresponding to a first electromagnetic field signal (EMR signal) from the first communication receiving unit 1011 (for example, the same as to or similar to the first communication unit 513 of FIG. 5 or the third circuit 630 of FIG. 6), and may receive a button input signal B that is sensed, according to whether the button switch SW1 is turned on or off, by the button input sensing unit 1013.

Referring to FIG. 10, according to various embodiments, the control circuit 1030 may include a first AND gate 1031 and a second AND gate 1033. When an approach signal A is received, and when the button switch SW1 615 is turned on, that is, when the value of the approach signal A is 1, and when the value of the button input signal B is 0, as in Table 1 above, the control circuit 1030 may perform an operation as in Equation 1 below by the first AND gate 1031, thereby calculating the value of the EMR button EMR BUTTON, and may perform an operation as in Equation 2 below by the second AND gate 1033, thereby calculating the value of the inverted BLE button BLE BUTTON. The first control circuit 1030 may acquire 1 as the value of the EMR button EMR BUTTON by the first AND gate 1031, and may acquire 0 as the value of the inverted BLE button BLE BUTTON by the second AND gate 1033.
